Basic Line Modules

Заказные данные
(24)

Basic Line Modules (BLM) are compact line infeeds for two-quadrant operation, i.e. no regenerative feedback.

They are used when energy need not be fed back into the network.

If regenerative conditions occur in the drive line-up, Braking Modules must be used because they convert the excess energy into heat in braking resistors.

Basic Line Modules are suitable for connection to grounded TN/TT and non-grounded IT systems. The following voltages and power ratings are available:

Line voltage	Rated power
380 ... 480 V 3 AC	200 ... 900 kW
500 ... 690 V 3 AC	250 ... 1500 kW

The power ratings can be increased by connecting up to four identical Basic Line Modules in parallel.

For an infeed with the Basic Line Modules, depending on the line short-circuit power, a line reactor should be provided at the connection point. This reactor is available as standard in the Line Connection Module. However, it can be omitted if it is not required (option L22).
For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.

The Basic Line Modules are available in different frame sizes.

With frame sizes FB and GB, a fully controlled thyristor bridge is used to pre-charge the Basic Line Modules and connected Motor Modules. The thyristors normally operate with a trigger delay angle of 0°.

Basic Line Modules, frame size GD for 900 kW (400 V) or 1500 kW (690 V) include a diode bridge, and the DC link is pre-charged via a separate line-side pre-charging device that is located in the Line Connection Module (option L43, Line Connection Module for Basic Line Module).

Parallel connection of Basic Line Modules to increase power rating

Line Modules can be connected in parallel (relative to the line supply) in two ways for the purpose of creating drive line-ups with a higher power rating.

Two Basic Line Modules supplied with power via two separate Line Connection Modules

With this arrangement, each Basic Line Module is supplied via a Line Connection Module and the Basic Line Modules are protected by fuses or circuit breakers (at I > 800 A) in the Line Connection Module. A Basic Line Module is assigned to a Line Connection Module and is mechanically coupled. It is not necessary to mechanically directly couple both "groups" comprising Line Connection Module and Basic Line Module. Other modules can also be inserted in between.

Two Basic Line Modules supplied with power via a single Line Connection Module

Basic Line Modules are available that can be operated on a single Line Connection Module. These can be connected to the left and right of the Line Connection Module. The power connections on the Basic Line Module on the left of the Line Connection Module are a mirror image (article no. with "C" in the next to last position, example: 6SL3730-1T.41-.BC3), which results in a very compact design for the line infeed.

For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.

These module versions feature integrated line-side fuses which are required because the circuit breaker in the Line Connection Module is not capable of providing selective protection for the Basic Line Modules. They are therefore 200 mm wider in each case than version 6SL3730‑1T...‑.AA3.

Note:

If the Basic Line Modules are supplied with power via the same circuit breaker, line-side fuses are provided to ensure selective individual protection of the modules. This arrangement increases the cabinet width by 200 mm (dimension data in selection tables includes extra width).

Please note that only Basic Line Modules with exactly the same output rating may be connected in parallel. The potential for imbalances in current distribution means that current derating of 7.5 % applies and this must be taken into account when the modules are dimensioned.

A connection of the Basic Line Modules connected in parallel using DRIVE-CLiQ must be taken into consideration.

For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.
